today, the president is in iowa, colorado, california, and nevada. the blue line, his campaign blitz just today and tomorrow. while mr. romney is going to hit nevada and iowa. the red line shows his flight plan for today. and vice president joe biden and congressman paul ryan are crossing paths in ohio, another very critical state. and that's why cnn has dispatched the best of the best. chief business correspondent ali velshi and john avalon on the cnn election express battleground bus tour. all right. so looks like you are both on vacation. let's just start with the picture behind you. i want that assignment. but it's going to get real tough. i've lived on a bus before for a month or so, and it's no fun. so let me start with the business of it. ali, to you first. we just showed a very big map to cover for these candidates. i'm wondering if in some of your driving, and this is highly unscientific, are you seeing the lawn sign metric? are you seeing more romney/ryan signs than obama/biden signs, or is it too early in your tour to tell me that? >> well
